How to Remove Skunks From Under a House Safely

If you are dealing with skunks under your deck, you need a plan that scares them off without putting you or the animal in danger. This is the exact problem behind “how to deter skunks from under deck” searches, because the space under a house is warm, quiet, and easy to hide in. The smartest approach is to identify what is happening first, protect everyone nearby, then block entry only after the den is empty.

Spot the Signs Before You Go Under the House

Before you approach the area, confirm you are dealing with a skunk and not another wildlife animal. A quick inspection from a safe distance helps you decide whether to proceed, wait, or call wildlife control.

Confirm it is really a skunk

Look for the combination of odor and behavior. Skunks have a sharp, pungent smell that hits quickly, and their tracks often show five claw marks in front and four behind. You may also see torn soil, overturned mulch, or shallow digging that looks like it is chasing grubs. If you hear scratching or scent changes near the foundation at dusk or night, that strongly points to a skunk using the space.

Look for burrow entrances, droppings, and odor

Scan the perimeter for entry points under the deck, steps, porch, or crawl-space openings. Use a flashlight from the outside only, do not crawl in. Skunk droppings can show up along travel paths, often left in small, dark piles near the den area. Fresh odor near one specific gap or along a narrow route is a key clue that you found the active area.

Check whether young kits may be present

Kits change the entire plan. If you see small skunks, multiple scent hotspots, or evidence of recent activity near the den, assume babies are possible. Skunks can be driven out of a den by people, but sealing too early can trap kits inside and cause panic. If there is any chance of young, keep people and pets away and use wildlife professionals to handle removal.

Know when to stop and call wildlife control

Stop and call a licensed wildlife professional if the crawl space is tight, if you cannot clearly identify all entry points, or if the skunk is acting agitated. Call if the den is near a roofline or wall cavity, or if you smell odor that keeps getting worse, which can mean multiple animals or trapped animals. Also call if you suspect babies, or if you have health risks that make close handling unsafe.

Keep People, Pets, and the Skunk Safe

Your goal is to stop contact, prevent spraying, and give the skunk a clear way out. When you rush, you corner the animal, which increases the spray risk.

Give the animal room to leave

Start by keeping everyone away from the under-structure area. Close nearby doors to rooms that connect to the space if possible, and keep a 25-30 feet distance from any visible skunk. If the skunk is inside a crawl space, avoid banging or crawling under structures. Let it move out on its own, especially during dusk and early night when it is most likely to travel.

Keep dogs and cats indoors

Bring pets indoors and keep them on leash if you must go near the perimeter. Dogs and cats can escalate quickly, and even a brief confrontation can cause spray. Put litter boxes and water inside so pets do not try to dart back out. If a pet has already gotten sprayed, contact a vet and treat the area carefully, because skunk odor spreads fast.

Avoid blocking the den while the skunk may still be inside

Do not trap, do not wedge boards into gaps, and do not place objects directly at the opening. Even a “temporary” block can prevent an animal from leaving. If the skunk still has access to multiple escape paths, it is more likely to exit calmly. You should also avoid covering vents or grates that connect to the den until removal is complete.

Use gloves, boots, and a flashlight if you must inspect

Only inspect from outside and do not put your face near a gap. Wear thick gloves, boots with closed toes, and long sleeves, and use a flashlight that lets you keep your distance. If you get close enough to smell strongly, step back. If you see the skunk moving toward you or refusing to leave, stop the inspection and back away.

Use Humane Ways to Encourage Skunks to Leave

Humane deterrence focuses on making the area less comfortable and less rewarding for the skunk. Use these actions while the animal is still deciding whether to leave.

Make the area less attractive with light and noise

Skunks prefer quiet cover. Turn on bright motion-activated lights aimed toward the underside of the deck or along the foundation line. Add a radio set to a low volume near the edge of the problem area, and place it where it cannot be knocked over. Start at dusk, keep it consistent, and do not crowd the skunk with sudden close-range actions.

Remove easy food sources around the foundation

Skunks return for meals. Pick up pet food bowls, store dry food in sealed containers, and remove fallen fruit. Keep trash secured in lidded bins and check for gaps that allow access. If you have grubs, treat the yard through lawn care steps, but focus first on removing the immediate food around the foundation.

Try one-way exit options only if the den is active and clearly mapped

A one-way device is meant to let the skunk escape, not trap it inside. Use it only when you know the den location and you have mapped the main entrance. The device must allow exit but block re-entry, and you must ensure there are no other openings the skunk can use to come and go. If the den is in multiple places or you cannot locate them, call a professional.

Wait for nighttime movement before sealing anything

Sealing is the last step. Do not close gaps during daylight if the skunk might still be inside. Observe from a safe distance at dusk to see whether the skunk leaves and whether it returns. If you plan to use exclusion materials later, wait until nighttime movement stops and the area stays inactive.

Seal the Entry Points the Right Way

Sealing prevents repeat visits, but only if the den is empty. The wrong timing can trap the animal inside a crawl space or under a porch.

Close gaps only after you are sure the den is empty

Confirm the den is empty before sealing. If you cannot confirm, assume it is active and use wildlife control. After removal, allow a reasonable period for activity to stop and re-check the openings from outside. This prevents trapped animals, panic, and the need for a second removal.

Reinforce weak spots under decks, porches, sheds, and houses

Skunks dig to reach shelter. Inspect the underside of decks, porch areas, shed foundations, and crawl-space seams for gaps. Pay attention to areas around damaged lattice, loose skirting, and corners where wood meets foundation. Reinforce these weak spots so a skunk cannot widen a gap and enter again.

Use sturdy materials that skunks cannot dig through

Skunks can push through flimsy barriers. Seal openings 1/2 inch or larger with 1/4-inch hardware cloth, not chicken wire. For holes and cracks, use durable materials like metal flashing and rigid patching, then cover with hardware cloth at the edges if needed. Secure everything with screws and blocking so it stays firm when the ground shifts.

Add a buried barrier or apron to stop future digging

Surface sealing alone can fail if a skunk digs under. Install a buried barrier or apron along the perimeter where entry is likely, using hardware cloth buried at least 12 inches deep. When possible, extend it outward to stop tunneling. This is what makes the exclusion last, especially under decks and sheds where digging is easy.

Prevent Skunks From Returning

After you remove the skunk and seal entry points, prevent the next one by removing incentives and improving exclusion details.

Keep trash, pet food, and compost secured

Use lidded garbage bins and lock-up storage for trash if animals keep breaking in. Feed pets indoors, and do not leave bowls outside overnight. Compost should be contained in a secure bin with a tight lid. Skunks also investigate spills, so clean up any food residue around the foundation.

Trim brush and clear hiding spots near the foundation

Dense brush and stacked wood make cover close to your home. Trim shrubs away from the foundation and clear weeds and leaf piles along the edges of your deck and crawl-space entrances. Store firewood off the ground and away from the underside of structures. Less cover reduces the chance a skunk chooses your yard as a daytime rest area.

Fix crawl-space vents and damaged lattice

Check vent screens for gaps and replace any torn or loose mesh. Repair damaged lattice, skirting, or fascia where a skunk could squeeze in. Use hardware cloth for vent coverage when appropriate, and secure it so it cannot be pushed out. These small fixes stop new entry attempts after exclusion.

Check for new digging after rain or thaw cycles

Rain and thaw cycles often trigger activity and uncover grubs or soften soil, making digging easier. Walk the perimeter after major weather and look for fresh holes, overturned soil, or new scuffed paths. If you find new digging, address it immediately by reinforcing the exact spot, not by only sealing the original opening.

Handle Roof or Shed Situations With Extra Care

Rooflines, walls, and sheds add complexity because skunks can get into multiple cavities and hidden entry routes.

Recognize when the problem is in a wall, attic, or roofline

If the odor or sounds come from inside a wall, attic, or near the roof edge, do not treat it like a simple under-deck opening. Watch for where the skunk travels, including along siding seams and eaves. If you cannot map the den with clear external openings, wildlife control is the safer option.

Avoid climbing onto a roof or sealing an opening too early

Do not climb onto a roof to “find the hole.” Falls and hidden cavities are a real hazard. Also avoid sealing the first opening you find, because the skunk may have alternative routes. Early sealing can trap the animal in a wall or roof space and create a difficult odor and removal situation.

Treat sheds and outbuildings like small dens with multiple exits

Sheds often have crawl spaces, undersides, and gaps around the foundation. Inspect around doors, skirting, base seams, and any vent areas, because skunks can enter and exit through more than one spot. Give the animal options to leave using humane exclusion steps only after you locate the main entrances. If you cannot verify a single den entrance, use a professional.

Know when odor cleanup may be needed after removal

If you had spraying or heavy odor saturation, cleanup matters after the animal is out. Wear gloves, avoid spreading the smell into living areas, and follow odor-neutralizing products designed for skunk odor on affected surfaces. For fabrics and porous materials under decks, replacement may be the fastest fix. Address odor after removal so you do not trap an active animal during cleaning.

Frequently Asked Questions

Is it safe to try to remove skunks yourself?

Only attempt DIY removal if you can confirm the skunk is already outside the den and can leave freely, with no chance of babies being trapped. If you suspect kits, if the space is tight and hard to access, or if the skunk is acting aggressive, a licensed wildlife professional is the safest choice. Skunks can spray when cornered, and under-house spaces are risky to enter.

How do I stop skunks from digging under a deck or shed?

Remove food attractants near the foundation first, including pet food, unsecured trash, and compost access. Then block access using exclusion materials that skunks cannot dig through, especially 1/4-inch hardware cloth, plus reinforcement at seams and weak corners. Prevention works best after the skunk is gone, because sealing while it is still inside can trap the animal.

Can I just seal the opening to make the skunk leave?

Do not seal an active den. Sealing can trap the skunk inside and cause panic, which increases odor and can lead to repeat problems. Young skunks may be left behind if you close too early. Wait until the den is empty and activity stops before closing gaps.

What attracts skunks under houses and porches?

Skunks seek shelter, warmth, and quiet cover, which is exactly what space under decks and porches offers. Food nearby makes the location even more attractive, including pet food left outside, open trash, and grubs or insects in the yard. If your foundation area stays undisturbed and has consistent food sources, skunks will keep returning.

When should I call wildlife control?

Call wildlife control if the skunk is acting sick, if you suspect babies, or if the den is under a tight crawl space, wall cavity, attic, or roofline. You should also call if you cannot identify all entry points or if the under-structure access is unsafe for you to reach. Professionals can handle humane removal and proper exclusion so the problem does not come back.
